AEM dispatcher cache clear after package deployment

Hi,

I'm having an issue with content which is deployed from author and replicated to publisher as a package does not trigger dispatcher cache invalidation. However the same content when activated as an individual asset from author invalidates dispatcher cache immediately after replication to publisher. I can see that when the package deployment takes place from the author it successfully deploys on publisher and the package gets deployed. If I add query string parameter to bypass dispatcher cache I'm able to get to the newly deployed content. But without query string parameter the dispatcher still serves the old content. It seems that the content replicated as a package does not clear dispatcher cache the same way as when activated as an asset. I updated the dispatcher configuration to  /statfileslevel "0" but still it is not working as expected. Thanks for any suggestions.
